Abstract: Un procédé pour préparer des liposomes consiste à dissoudre un lipide formant une membrane liposomique dans un solvant organique, à éliminer par distillation le solvant de la solution, à ajouter au résidu une solution aqueuse constituée de diverses substances, à soumettre la solution à des vibrations ou à des ultrasons afin de préparer une suspension homogène, à pressuriser la suspension au moyen d'un gaz inerte afin de permettre une infiltration suffisante du gaz inerte dans la suspension, puis à éjecter par une fente la suspension sous une pression élevée. La viscosité de la solution aqueuse est de préférence comprise entre 10 et 3000 cP (20°C), et la pression appliquée par le gaz inerte est de préférence comprise entre 80 et 130 kg/cm2. Ce procédé permet la préparation de liposomes contenant une solution aqueuse qui renferme dans une concentration élevée un composé de poids moléculaire élevé, permettant ainsi une plus large utilisation des liposomes. Est également décrit un liposome contenant une solution d'hémoglobine aqueuse, dans lequel la membrane liposomique comporte comme constituant principal un phospholipide hydrogéné à un degré d'hydrogénation égal ou supérieur à 50 %, et dans lequel la solution d'hémoglobine aqueuse présente une concentration en hémoglobine de 30 à 60 % (eau/volume). Dans cet hémosome, la membrane est constituée d'un phospholipide naturel hydrogéné à un degré d'hydrogénation égal ou supérieur à 50 % et présente une résistance à l'oxydation suffisante, de sorte que la conversion d'hémoglobine en méthémoglobine est diminuée. D'autre part, puisque l'hémosome contient de l'hémoglobine sous forme d'une solution aqueuse concentrée incorporée dans le liposome, la quantité de phospholipide constitutif de la membrane peut être relativement réduite par rapport à la quantité d'hémoglobine, ce qui permet d'améliorer considérablement la sécurité. En outre, puisque la concentration de la suspension d'hémosome peut être réduite, sa viscosité peut l'être également, ce qui est avantageux pour la

Abstract: A central station (SC) is connected in series with the stations by a looped connection comprising a message loop (BM), a clock-signal loop (BH) and a state-control loop (BCE). Each station comprises an interface (I) connected to the various loops of the connection. The message loop routes messages transmitted by the central station destined for at least one interface, the responses from the interfaces, and messages transmitted by the interfaces destined for the central station. The clock-signal loop routes a clock signal transmitted by the central station and the state-control loop routes a state-control signal transmitted by the central station, this signal having a first value for a drive mode of operation and a second value for a reserve mode of operation of the interfaces; the passing from the first to the second value enables the control of a reset to zero of the interfaces. The clock and state-control signals have the same circulation sense, the messages having an inverse circulation sense.

Abstract: The invention relates to a process and a device for chemical deposition on a substrate, from at least one gas phase containing the elements to be deposited. The process consists in circulating the gas phase successively through two distinct zones, namely a first electronic activation zone (Ze) in which at least a fraction of the gas phase is subjected to an alternating electronic field to ensure the formation of a cold plasma and a second thermal activation zone (Zt) in which is placed a substrate (S) which is heated to a temperature appropriate for bringing about the deposition. The two zones are decoupled both thermally and electrically. The process of the invention, which thus leads to operating the two activation modes separately without significant interaction between them makes it possible to reduce very considerably the process temperatures in the thermal activation zone and to work over a very broad range of pressures. <IMAGE>

Abstract: A feed containing C₆ cycloparaffins, C₆ normal paraffins, and higher boiling hydrocarbons is charged to an isomerization zone to simultaneously open the rings of cyclic hydrocarbons and to isomerize normal paraffins and a single fractionation zone is used to separate the feed and the isomerization product into a C₇ plus stream that can be used as a feed stream to a reformer and an isoparaffin product stream consisting of C₆ and lighter hydrocarbons that is deficient in cyclic hydrocarbons. The isomerization zone uses a chlorided platinum-alumina catalyst to simultaneously open rings and isomerize C₆ hydrocarbons. This process offers a simple flow scheme that yields a high volume of high octane isomerate while reducing the quantity of C₆ cyclic hydrocarbons in a reformer feed by converting the C₆ cyclic hydrocarbons to isoparaffins, thereby reducing the benzene yield from the reformer feed while also increasing the combined liquid volume yield.

Abstract: A precision liquid dispenser comprises a positive displacement diaphragm pump and a hydraulic system for selectively deforming the diaphragm. The diaphragm pump comprises: pump body 109, pump cavity 110, pump diaphragm 111, and pump input/output port 117. A solenoid operated valve assembly 125 selectively connects the port 117 to a source of liquid to be dispensed 113 and to an output filter 123. 
     A hydraulic system for selectively deforming diaphragm 111 comprises: body 104 with cavity 106, piston 107, sealing ring 108 and hydraulic fluid in the space between the top of piston 107 and diaphragm 11. The position of piston 107 is controlled by the stepping motor 102 and the mechanical coupling of the output shaft of the motor to the piston 107, Mating threads on the shaft 120 and on the interior of the member 121 convert rotary motion of the motor output shaft to linear motion of the piston 107. 
     The volume of fluid dispensed per cycle of dispenser operation is determined by the number of pulses applied to the stepping motor 102; and the output flow pattern as a function of time is controlled by the pattern of pulses applied to motor 102 by the control logic 150.   
     The solenoid valve assembly 125, under the control of signals from the dispenser control logic 150, selectively connects the valve input port 115 to the valve input/output port 116, or connects the input/output port 116 to the valve output port 112. Valve control signals from control logic 150 are coordinated in time with control signals for the reversible motor 102 over path 151.
